A man armed with a gun robbed a Bad Ass Coffee on Crater Lake Avenue in Medford Tuesday night.

The suspect approached the barista just before 9 p.m. and displayed a weapon before fleeing with an undisclosed amount of cash. A Medford police officer who was patrolling nearby arrived on the scene within a minute, but was unable to locate the suspect.

"There are apartments just to the east of that location in which the suspect could scurry into," Medford police Sgt. Mark Boone said.

Officers surrounded the area and deployed a tracking dog, but no sign of the robber turned up.

No one was injured during the robbery attempt.

The man stood approximately 5 feet 7 inches tall and is described as a white male adult.

Police are asking that anyone in the area call police dispatch with tips at 541-770-4783.
